It’s an interesting one because I’m sure I disabled the Escape key!
Just to confirm you are exiting the game via the Main Menu normally, right?

Clearly something in the shutdown process is failing… and I suspect the fact you have an AMD Radeon could be significant… I know these cards can sometimes behave differently and I could only test the game on the GeForce range.

So to solve a potential Radeon issue will not be easy but I’ll review the shutdown code to see if I get any ideas of how to debug further…
